Use Case Modeling in Software Development: A Survey and TaxonomyEswar Publications
Identifying use cases is one of the most important steps in the software requirement analysis. This paper makes a literature review over use cases and then presents six taxonomies for them. The first taxonomy is based on the level of functionality of a system in a domain. The second taxonomy is based on primacy of functionality and the third one relies on essentialness of functionality of the system. The fourth taxonomy is concerned with supporting of functionality. The fifth taxonomy is based on the boundary of functionality and the sixth one is related to generalization/specialization relation. Then the use cases are evaluated in a case study in a control command police system. Several guidelines are recommended for developing use cases and their refinement, based on some
practical experience obtained from the evaluation.

First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.

How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.

UML Unit 01
1. Objectives
In this lesson, you will learn about :
Object-oriented modeling
Origin and evolution of UML
Architecture of UML
User View
Actor
Use Cases
2. The Object Oriented Approach
The object-oriented approach views a system as a
collection of real-world objects
Object-oriented systems are based on classes
A class categorizes a set of objects that share
common
Attributes - represent the properties of the class
Behaviors - represent the operations that can be
performed by the class
An object is an instance of a class and demonstrates
the attributes and behaviors of the class
3. Features of Object-Orientation
Abstraction - represents the essential characteristics
of an object or a class that differentiates it from other
objects or classes with respect to the viewer’s
perspective
Inheritance - helps you generalize common attributes
and behaviors in separate classes from which various
subclasses can be derived
Encapsulation - helps you hide unnecessary
behaviors or attributes from the user
Polymorphism - is the ability of an object to behave
differently under different circumstances
4. Software Development Life Cycle
Software Development Life Cycle consists of four
phases that any software-intensive system undergoes
Inception - This is the first phase of the SDLC process.
The idea of a new system is envisaged at this stage
Elaboration - This is the second phase of the SDLC
process. The system vision and architecture are defined
at this stage
Construction - This is the third phase of the SDLC
process. The software is coded to form an executable
base, which is ready to be deployed
Transition - This is the last phase of the SDLC process.
The software is handed over to the end user and is
tested for defects
5. Object-Oriented Modeling
Modeling is breaking the complex problem into small
elements and arriving at the solution of the problem
Models help you visualize and specify different parts
of a system
Models also show how different parts are related to
one another and help in visualizing their working
6. Object-Oriented Modeling(Contd.)
UML defines various models in the software
engineering domain. The models and their description
are given below:
The class model describes the static structure
The state model represents the dynamic behavior of
objects
The use case model explains the requirements of the
user
The interaction model describes the messages flows
The implementation model contains the work units
The deployment model contains details that pertain to
process allocation
7. Unified Modeling Language (UML)
Is a standard modeling language used for modeling
software systems of varying complexities
Provides a set of notations and rules for using any kind
of system
Focus is on creating simple, well-documented and
easy-to-understand software models
8. Goals of UML
The goals of the UML are:
To provide a simple and ready-to-use expressive
visual modeling language
To be process-independent
To be language-independent
9. UML is used to:
Visualize the software system with well-defined
symbols
Specify the software system and help in building
precise, unambiguous, and complete models
Construct models of the software system that can
directly communicate with a variety of programming
languages
Document models of the software system by
expressing requirements of the system during its
development and deployment stages
10. Where is UML Used?
Some of the most common domains where UML is
being currently used are:
Banking services
Defense systems
Distributed Web-based services
Enterprise Information systems
Medical systems
Aerospace systems.
11. UML: The Big Picture
User View
Structural View
Behavioral View
Implementation View
Environment View
12. Views in UML
User View – represents the goals and objectives of the
system
Structural View – represents the static or idle state of
the system
Behavioral View – represents the dynamic or changing
state of the system
Implementation View – represents the distribution of
the logical elements of the system
Environment View – represents the distribution of the
physical elements of the system
13. Context and Environment of a System
A system addresses a problem and provides solutions
to the problem within a framework. This framework is
referred to as the context of a system
The environment of a system specifies the functionality
of the system from the user’s point of view
14. The User View of a System
Represents the goals and objectives of various users
and their requirements from the system
Represents that part of the system with which the user
interacts
Consist of:
System Users - System users can be human users
or other systems that interact directly with the
system
Actors - Actors are the elements that lie outside the
system, and therefore are called the external
entities of a system. They are used to model
system users
15. Actors
Are divided into four main categories:
Principal actors – people who directly interact with
the system.
Secondary actors – people who are involved in
maintenance of the system
External hardware – The hardware that is a part of
system other than the computer that runs an
application
Other systems –The external systems with which
your system needs to interact for its working
16. Problem Statement 1.D.1
One of the sources used by Tebisco for recruiting
personnel is the internal job postings process.
Whenever a vacancy arises, the Human Resource
(HR) head of the region informs all the employees of
that region and also sends the information to other
regional HR heads inviting applications. The other
regional HR heads then place the vacancy information
on the notice board. All interested employees send
their applications to the HR head of the region where
the vacancy exists.
Identify the various actors interacting with the system.
17. Solution:
The actors identified are:
Regional HR head where a vacancy exists, denoted as
RHR(V)
Other Regional HR head, denoted as RHR(O)
All employees of Tebisco, denoted as EMP
18. Problem Statement 1.P.1
Employee referrals are one of the best sources used for
recruiting external candidates at Tebisco. In this process
an employee recommends a candidate. Whenever a
vacancy arises, the HR head of the region informs all the
employees of that region and also sends the information
to other regional HR heads inviting applications. The
regional HR head then places the vacancy information
on the notice board. Employees send the details of
candidates being recommended by them to the HR head
of the region where the vacancy exists. After an
employee sends in the recommendation, the regional HR
head sends an acknowledgement of the receipt of the
application to the candidate.
Identify the various actors interacting with the system.
19. Use Cases
Consist of elements that lie inside the system
Are responsible for functionality and behavior of the
system
Are set of transactions performed by the system when
an actor initiates an event or an action
Represent all the possible events that can occur in all
possible scenarios
20. Diagrammatic Conventions for Drawing
Use Case Diagrams
The user view of a system consists of use case
diagrams
A use case diagram contains actors, use cases, and
their relationships
A use case diagram represents the functionality
provided by the system to external entities
Use case diagrams consist of actors and use cases
21. Diagrammatic Conventions for Drawing
Use Case Diagrams(Contd.)
Following is the diagrammatic representation of use
case diagrams
<Actor Name>
<Use Case Name>
22. Diagrammatic Conventions for Drawing
Use Case Diagrams(Contd.)
Consider the following examples of use cases in the
billing system of the department store:

24. Problem Statement 1.D.2
In the internal job postings process, the HR head of the
region where a vacancy exists informs the employees of
that region and other regional HR heads. The other
regional HR heads inform employees by putting up a
notice with the vacancy information.
In response to this information, employees from various
regions send their applications to the HR head of the
region where the vacancy exists.
The skills of the applicants are then matched with the
skills required for the vacancy. Applicants who possess
the required skills are short-listed and an interview
schedule is drawn. The short-listed applicants are
informed about the interview schedule.
25. Problem Statement 1.D.2 (Contd.)
Based on the interview proceedings, interview details are
updated and all the selected applicants are given a new
